the introduction of MvcUriComponentsBuilder (inspired by Spring HATEOAS)

and last but not least, a lot of fine-tuning in Spring’s new WebSocket support

Overall, this is the perfect time to give Spring Framework 4.0 an early try! We’ll make sure to incorporate your feedback in a timely fashion on our way to 4.0 GA in December.

Note: We are aware that current Spring Web Flow and Spring Web Services are not working with Spring Framework 4.0 RC1 at this point, due to dependencies on deprecated classes which got removed in 4.0. We are in the process of addressing this in time for 4.0 GA.

Enjoy!
